BVEM Bottom feed vibro-replacement vibroflot stone column pile driver

Development & Application of Vibroflotation

Applicated by Europ in 1930s with Vibro-compaction. Since 1970s vibro-replacement has been developing. In China, vibroflotation was launched in 1977 by BVEC company and developed rapidly in construction industry.

Vibroflotation bring an effective good result to soft soil even it use simple, convinient and cheap equipment and material. Construction organization and construction process are simple. It is recognized to be a practical application

Bottom feed vibroflotation characteristics

1.can be used for construction in silt clay soil improvement with non-drainage shear strength less than 20kpa

2.used for vibroflotation constsuction on offshore project

3.adopt to dry vibroflotation method , protecting earth better

4.quality of stone column pile can be controled more easily

5.double lock pressure chamber structure can keep air pressure longer

6.Powerful compacting soil layers to achieve better results

7.strenght penetrating power can against the SPT value of hard soil layer more than 50 blows
